Sinus Floor Elevation Via the Maxillary Premolar Extraction Socket With Immediate Implant Placement: A Case SeriesWhen immediate implant placement is considered
for teeth with close proximity to the sinus floor, apical
extension of the osteotomy is significantly limited, and often
a staged approach is used. Implant placement into fresh extraction sockets and sinus floor manipulation using bone-added osteotome sinus floor elevation with implant placement
are techniques most often used independently or sequentially.
In this care report, immediate implant placement with simultaneous osteotome sinus floor elevation is an advantageous
combination of two successfully used techniques. This combined
approach can significantly reduce the treatment time
for implant therapy in teeth with close sinus proximity and provide the operator with the ability to place implants of desired length.

Alternative Applications of Guided Surgery: Precise Outlining of the Lateral Window in Antral Sinus Bone GraftingComputed tomography (CT) and the application of CT-based guided implant surgery allow clinicians to
provide enhanced precision and accuracy in implant surgery. Because of the difficulty in transferring a
patient’s often complex anatomic sinus configurations, as viewed on a preoperative CT scan, into precise
osteotomy cuts at antral bone graft surgery, a prototype cutting guide was developed. The surgical guide
was developed through the use of CT imaging and the stereolithographic process to precisely position the lateral window, facilitating schneiderian membrane elevation. This report demonstrates the step-by-step method to
perform precise guided sinus window preparation using computer software and a stereolithographically
generated surgical guide.

Sinus Augmentation for Single-Tooth Replacement in the Posterior Maxilla: A 3-Year Follow-up Clinical ReportA technique for single-tooth sinus lift and simultaneous implant placement in the posterior maxilla is presented. Ten hydroxyapatite-coated cylindric implants, 13 to 15 mm in length, were placed together with a composite bone graft of demineralized freeze-dried bone allograft and autogenous bone in 10 adults. Surgical technique and anatomic considerations are discussed. Follow-up of 3 years showed successful function and no cervical bone loss in all patients.

The Effect of Piezoelectric Use on Open Sinus Lift Perforation: A Retrospective Evaluation of 56 Consecutively Treated Cases From Private PracticesThe lateral window approach to maxillary sinus augmentation is a well-accepted treatment option in implant dentistry. The most frequent complication reported with traditional techniques has been the perforation of the Schneiderian membrane, with erforation rates ranging from 11% to 56%. The purpose of this retrospective, consecutive case series from two private practices was to report on the rate of Schneiderian membrane perforations and arterial lacerations when a piezoelectric surgical unit was used in conjunction with hand instrumentation to perform lateral window sinus elevations.

Maxillary Sinus Membrane Repair: Update on Technique for Large and Complete PerforationsMaxillary sinus membrane perforation is the most common complication that occurs with sinus elevation augmentation surgery. A technique using a slow resorbing type I collagen membrane for repair of large and complete sinus membrane perforations is described. The biocompatibility and semirigid structural integrity of this membrane, along with external tack fixation, allows for optimal membrane stabilization and maintenance. (Implant Dent 2008;17:24–31)
